Merge branch 'for-3.1' of git://linux-nfs.org/~bfields/linux
* 'for-3.1' of git://linux-nfs.org/~bfields/linux: nfsd: don't break lease on CLAIM_DELEGATE_CUR locks: rename lock-manager ops nfsd4: update nfsv4.1 implementation notes nfsd: turn on reply cache for NFSv4 nfsd4: call nfsd4_release_compoundargs from pc_release nfsd41: Deny new lock before RECLAIM_COMPLETE done fs: locks: remove init_once nfsd41: check the size of request nfsd41: error out when client sets maxreq_sz or maxresp_sz too small nfsd4: fix file leak on open_downgrade nfsd4: remember to put RW access on stateid destruction NFSD: Added TEST_STATEID operation NFSD: added FREE_STATEID operation svcrpc: fix list-corrupting race on nfsd shutdown rpc: allow autoloading of gss mechanisms svcauth_unix.c: quiet sparse noise svcsock.c: include sunrpc.h to quiet sparse noise nfsd: Remove deprecated nfsctl system call and related code. NFSD: allow OP_DESTROY_CLIENTID to be only op in COMPOUND Fix up trivial conflicts in Documentation/feature-removal-schedule.txt
